We use Lister, an old one, we can still get parts! We use a tool that shiller USES. We are mainly mules, some hair quality. The coal mining machine has about 120,000 sheep (wild entertainment!) in all farms. We have a lot of Swaledales around. Much depends on what you like and what you can afford. There is nothing to do with heing, but you need to consider the availability of the parts you get. Cut happy!
